<p>[QUOTE=&quot;Conder101, post: 1331220, member: 66&quot;]Gold coins from a lot of countries can probably be found to have traces of Mercury in them.&nbsp; Mercury was used for centuries in the mining of gold.&nbsp; Powdered ore would be sluiced over Mercury and the liquid metal would dissolve the gold out of the slurry forming an amalgam.&nbsp; The amalgam would later be refined to recover the gold, but with as sensitive as out detection equipment is today you can probably still detect the Mercury.[/QUOTE]</p><p><br /></p>
